State-Changed-Why:
    I'm still leaning with Volker's ABI theory. What one
    would need to check is what libraries Qt actually pulls
    in. For example, on my system these are:
    tmp/g> ldd /usr/lib/libqt.so.3
            libpng.so.2 => /usr/lib/libpng.so.2 (0x40618000)
            libz.so.1 => /lib/libz.so.1 (0x40649000)
            libGL.so.1 => /usr/lib/libGL.so.1 (0x40658000)
            libXmu.so.6 => /usr/X11R6/lib/libXmu.so.6 (0x4080f000)
            libICE.so.6 => /usr/X11R6/lib/libICE.so.6 (0x40826000)
            libSM.so.6 => /usr/X11R6/lib/libSM.so.6 (0x4083e000)
            libdl.so.2 => /lib/libdl.so.2 (0x40848000)
            libXext.so.6 => /usr/X11R6/lib/libXext.so.6 (0x4084c000)
            libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x4085a000)
            libXrender.so.1 => /usr/X11R6/lib/libXrender.so.1 (0x4091a000)
            libXft.so.1 => /usr/X11R6/lib/libXft.so.1 (0x40920000)
            libfreetype.so.6 => /usr/lib/libfreetype.so.6 (0x4094a000)
            libstdc++-libc6.2-2.so.3 => /usr/lib/libstdc++-libc6.2-2.so.3 (0x4098a000)
            libm.so.6 => /lib/libm.so.6 (0x409d7000)
            libc.so.6 => /lib/libc.so.6 (0x409fa000)
            libXt.so.6 => /usr/X11R6/lib/libXt.so.6 (0x40b22000)
            libXi.so.6 => /usr/X11R6/lib/libXi.so.6 (0x40b70000)
            /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)
    
    
    On my system, these libraries all contain no C++ symbols,
    except libstdc++, of course, but you should repeat this
    with the executables/libraries that fail for you.
    
    Please understand that we do not want to push away
    responsibility for possible bugs to you, but that simple
    the problem you describe is so vague, and the piece of
    code in which it happens so large, that there is about
    no way for us to track this problem down. So we just
    try to eliminate the simple problems first.
